Chemical Information

FooDB Name

3-Hydroxy-2-pentanone

Description

3-Hydroxy-2-pentanone belongs to the class of organic compounds known as acyloins. These are organic compounds containing an alpha hydroxy ketone. Acyloins are formally derived from reductive coupling of carboxylic acyl groups. Thus, 3-hydroxy-2-pentanone is considered to be an oxygenated hydrocarbon. 3-Hydroxy-2-pentanone is a herbal and truffle tasting compound. 3-Hydroxy-2-pentanone is found, on average, in the highest concentration within beer. 3-Hydroxy-2-pentanone has also been detected, but not quantified in, asparagus (Asparagus officinalis). This could make 3-hydroxy-2-pentanone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3-Hydroxy-2-pentanone.
